Two Exits and Travel Distances to Each

First off, the 150' building length should be 300'. Oops.

Hypothetical 300'x150' F-1 open building, non-sprinklered with only two exits required. The dot represents a remote part of the building. Are the travel distances represented correct or will I get dinged for excess TD if one exit were to be blocked?

Approved, put a stamp on it

300 - 75 = 225 ft.; the travel distance to an exit shall not exceed 200 ft. (including the 75 ft. common path of travel).

I do not see any travel distance issues?

 

[Francis Vineyard]

In the event an exit is blocked, the common path of travel is from that (most remote) point to the next available exit IMO.

EXIT ACCESS. That portion of a means of egress system that leads from any occupied portion of a building or structure to an exit.

1006.2.1 Egress based on occupant load and common path of egress travel distance. Two exits or exit access doorways from any space shall be provided where the design occupant load or the common path of egress travel distance exceeds the values listed in Table 1006.2.1.

Looks like a compliant 200' to me...

When measuring travel distance, you can count all the exits - you don't have to assume one is blocked. Think about it, if you have to have three exits (or more), it could get really confusing how to decide what the travel distance is if you had to consider one (or more) blocked.

In most cases, spaces with two means of egress will generally have no common path of egress travel (CPET), unless the two separate paths merge somewhere down the line. CPET is not a factor when one of two or more exits are blocked -- CPET, as well as travel distance, assumes all exits are available.
